Add egroup-notification-master bypass
As mentioned in https://okd-internal.docs.cern.ch/computing-resources/global-resources/#for-email-notifications
wwwprot was requested to be added to https://e-groups.cern.ch/e-groups/Egroup.do?egroupName=egroup-notification-master in August 2023 to bypass posting restrictions on CERN e-groups used as admin groups of OKD4 projects.
So we should consider adding an extra check for membership on this egroup.
